Terrible service!

I was so impressed with the new dstv internet, but these past few months I have had the worst experiences thus far. I upgraded to the 110gb day and 110gb night package, but from day 1 I received problem upon problem. My data was supposed to be loaded on the 15th, but wasn't because of a delay with my debit order caused by my bank FNB. I didn't notice the data problem because my previous month's data wasn't used up. Since yesterday, 28th of October my data was depleted and I had to call dstv to find out how the hell that was possible, only to use up all my airtime (which they won't compensate me for) and to eventually find out that my new month' s data was never loaded. After struggling 3 times to sort this out I was assured that my data would be loaded within 3 hours. Guess what? More than 24 hours later, more conversations with dstv agents, more data and airtime that I had to load, still no data loaded on my router, but I paid for this service! And you aren't ever able to contact dstv and ask to be put through to the internet department. Dstv promise to have them call you back, but that hardly ever happens! I expect proper feedback in my case and I want to be compensated for all the extra expenses I had to incur because of this! Why must I go through these problems? This is outrageous!
